Cl. 131-194 1 Claim ABSTRACT OFTHE DISCLOSURE A cigarette holder having a socket for receiving acigarette at the inlet end, a mouthpiece at the discharge end and asmoke cooling member between the two. The socket has a screw threadedengagement with the inlet end of the mouthpiece and the smoke treatingmember adjacent to the socket member. The smoke treating member consistsof a plurality of smoke conducting tubes that are mutually spaced andcontained within a housing member that is placed in the inlet end of themouthpiece. The tubes are connected to apertured discs adjacent to theopposite ends of the member and communicate with chambers adjacent toeach disc and are so arranged that smoke passing through the holderreverses direction twice before reaching the discharge end of themouthpiece. A valve is provided in the chamber at the upstream end ofthe member and is arranged so that a cooling fluid such as liquefied gasmay be injected and retained under pressure within the housing in thespace surrounding the spaced tubes and between the apertured discs.

BRIEF SUMMARY It is well recognized that tobacco smoke containsingredients which can be unpleasant to smokers, and in some casesharmful as well. It is also recognized that in general, the higher thetemperature of the smoke, the greater will be the tendency thereof to beunpleasant and harmful.

It is an object of the present invention to provide a smokers devicesuch as a cigarette holder with means for cooling the smoke drawntherethrough by providing a divided smoke path consisting of pluraltubes that are mutually spaced and surrounded by a cooling medium and inaddition, to cause the smoke to traverse a smoke treating member threetimes in a serpentine path as it passes through the same.

For a better understanding of the present invention, attention isdirected to the accompanying drawing wherein:

FIG. 1 is a perspective view of a cigarette holder constructed inaccordance with the present invention;

FIG. 2 is a central longitudinal section through the holder shown inFIG. 1;

FIG. 3 is a cross sectional view taken on the line 3-3, in FIG. 2,facing in the direction of the arrows;

FIG. 4 is a view similar to FIG. 3, taken on the line 44, in FIG. 2;

FIG. 5 is a view similar to FIG. 3, taken on the line 55, in FIG. 2; and

FIG. 6 is a view similar to FIG. 3, taken on the line 6-6, in 'FIG. 2.

DETAILED DESCRIPTION The device shown in the drawing may be assembled bysliding a smoke treating member having cylindrical shell 14 into achamber provided therefor in the inlet end of the mouthpiece portion 19after which the socket 20 is connected thereto by screw threads tooccupy the positions shown in FIG. 2. The inlet end of the socket has aninternal shoulder for limiting the insertion of a cigarette therein andproviding a chamber between the unlit end of 'ice the cigarette and theinlet end of the smoke treating member. The central portion of thelength of the smoke treating member consists of a cooling chamber havingan apertured disc 13 at the inlet end and another apertured disc 16 atthe discharge end, both discs being mounted in sealing relation with theinternal wall of the shell 14. Mounted between the discs, and spacedfrom each other and from the internal wall of the shell are a pluralityof smoke conducting tubes 14, 17 and 18, arranged so as to be parallelto each other and to the longitudinal axis of the cooling chamber andthe holder. Each tube is mounted at the opposite ends thereof in sealingrelation with each of the discs 13 and 16, and is in communication withan aperture in each of said discs. A third disc 2 is mounted at theinlet end of the shell 14 in spaced relation with the disc 13. Apartition 10 is mounted in sealing relation between the discs 2 and 13,and with the internal wall of the shell providing smoke receivingchambers 3 and 9. The disc 2 is provided with an opening 1 as seen inFIG. 3, so that smoke may pass into the chamber 3. Similar smokereceiving chambers 6 and 7 are provided at the discharge end of thesmoke cooling member and are defined by the discs 16 and 12 and thepartition 8 which is mounted and sealed in the same manner as thepartition 10. The disc 8 has a discharge opening 11 as seen in FIG. 6,which is arranged in diametrically opposed relation to the opening 1. Aspring loaded valve 15 is mounted between the discs 2 and 13 by means ofa casing or duct 21 and is adapted to provide means whereby a coolingmedium such as liquefied gas for example, liquefied nitrogen, may beinjected into the cooling chamber to occupy the space '5 under pressureand to surround the tubes therein.

In use, a cigarette is placed in the inlet end of the socket 20 untilunlit thereof abuts the shoulder, and is lit in a conventional fashion.As the user draws on the mouthpiece end of the holder, smoke is drawnfrom the cigarette into the chamber in the discharge end of the socket20, through the opening 1 into the smoke receiving chamber 3, throughthe plural tubes 4 shown in the lower portion of FIG. 2, into thechamber 6. The smoke then reverse direction and flows through the tubes17 to the chamber 9 where the smoke then reverses direction a secondtime and flows into and through the chamber 7, through the opening 11,through the discharge end of the mouthpiece 19 and into the mouth of theuser.

After being used, the smoke cooling member may be removed after thesocket 20 is unscrewed from the mouthpiece 19, it being noted that thedischarge end of the socket includes a shoulder portion adapted to holdthe member in the holder between a similar shoulder in the mouthpiece,adapted to engage the discharge end of the member. As noted in FIGURE 2,the shell 14 is made from heat insulating material. The remainder of thecooling member may be made from metals which can be joined by soldering,welding or the like. The socket and the mouthpiece are made frommaterials conventionally used for that purpose. The cooling member maybe charged by the smoker prior to using the holder, or the coolingmember may be provided to the smoker in charged condition.

According to the above, it will be seen that smoke passing through thepresent holder will be cooled as it passes through the tubes 14, 17 and18, and in the chambers 3, 6, 9, and 7, and by virtue of the reversingpassage provided, the smoke will be divided into plural streams,assembled after each pass, and redivided as it is caused to reversedirection each time, thereby providing plural opportunities for the heatthat is contained in the smoke to be extracted by the coolant gas in thecooling member thereby lowering the temperature of the smoke and caus-Ing condensation of tars and the like that may be en- ;rained therein.

Having thus described my invention, I claim:

1. A smoking device having means for holding tobacco 10 be burned at oneend, a mouthpiece at the other end and a smoke conducting and treatingmember therebe- LWeen, said member including a casing connecting the:obacco holder and the mouthpiece and containing plural spaced smokeconducting conduits extending longitudilally thereof and in mutuallyspaced relation therein, neans comprising a pair of discs extendingtransversely )f the member, said discs being attached to opposite endsat said conduits and being supported in said member by Jeing attached atthe peripheral portions thereof to a casng surrounding said discs andsaid conduits, said mem- 361' having means for retaining said casingtherein, said :asing having chambers at opposite ends thereof wherebysaid discs are spaced from the ends thereof and providing :hambersadapted to direct the flow of smoke through the device, said casinghaving apertured Walls at the opposite ends thereof adapted to permitsmoke to pass therethrough and partitions extending longitudinally ofsaid chambers and extending thereacross, the discs having a plurality ofapertures therethrough and said conduits being attached ;0 said discs sothat smoke which may be made to flow through each aperture will flowthrough a conduit in communication therewith, the conduits beingarranged to provide a serpentine path through said conduits and chambersin said casing from the tobacco holder to the mouthpiece, the end walland the disc located nearer said tobacco holding member'having a ducthaving a spring loaded valve therein and extending axially therethroughwhereby a fluid coolant under pressure may be forced through said ductand into said casing so as to surround said conduits in said member.
